How can I incorporate the CXN V2 into a multiroom system?

As the CXNV2 includes Chromecast Built-in this will allow you to add the CXNV2 to a Cast speaker group. Once added you will be able to Cast audio to multiple speakers at the same time.

To add the CXNV2 to a Cast speaker group please follow the instructions below:

1. Ensure all Cast speakers and CXNV2 are on the same network.

2. Download the Google Home app from the App Store (iOS device) or the Play Store (Android device).

3. Once download you should find all available Cast speakers on your network. The app will break these down to show speakers you have assigned to a particular room and also list all unassigned speakers as 'Local devices'.
